Covid-19 testing system is reaching a brink as growing demand surpasses what the nation’s labs can handle, sparking supply shortages and backlogs
If you’re Black in America, Covid-19 is more likely to kill you, and the disparity has only widened as cases have surged across the U.S.
This was the week airborne transmission became a big deal in the public discussion about covid-19. Over 200 scientists from around the world cosigned a letter to the World Health Organization urging it to take seriously the growing evidence that the coronavirus can be transmitted through the air. WHO stopped short of redefining SARS-CoV-2 (the virus that causes covid-19) as airborne but did acknowledge that more research is “urgently needed to investigate such instances and assess their significance for transmission of COVID-19.”
For months, California hospitals avoided the dreaded surge in coronavirus patients that threatened to overwhelm wards and stretch thin staff and supplies. But now, with coronavirus hospitalizations in the state at an all-time high, doctors and nurses at some hospitals say the nightmare has arrived.
Evidence suggests that children aren’t as susceptible as adults to COVID-19, but the risks aren’t the same for all young people.
The SARS-CoV-2 pandemic has revealed the limitations of R0 as no other disease outbreak has before, at a time when policymakers need accurate forecasts.
Hong Kong ordered gyms and bars to close for a week, restored strict limits on public gatherings and introduced fines for anyone refusing to wear a mask on public transport in a fresh bid to prevent the resurgent coronavirus from spiraling out of control.
10 Minute Audio at the link – The Australian state of Victoria, which includes Melbourne, just started a new six-week lockdown. The state just recorded a record number of new daily cases: 191. Education and public health experts agree it’s important that kids get back to school in the fall. The question is how to do it safely. NPR’s Anya Kamenetz reports on some radical ideas for reopening.
New York City, once the epicenter of the nation’s coronavirus outbreak, has just reported its first day with zero confirmed or probable virus deaths since the pandemic hit New York State.
Four months after the start of the coronavirus pandemic, doctors are still on a steep learning curve. One surprise is just how long symptoms seem to last, for some patients. Dr John Wright of Bradford Royal Infirmary (BRI) talks to two young women who are still tired and breathless many weeks after falling ill.
The patient in the case report was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis.
As the coronavirus pandemic rapidly evolved into a public health crisis of global proportions, doctors and scientists embarked upon a real-time journey to uncover how the virus mercilessly attacks various parts of the body and what to do about it. While medical experts have been troubled by the respiratory virus’ tendency to wreak havoc on the lungs, perhaps more puzzling has been its relationship with the heart.

Science and Tech
Before public health officials can manage the pandemic, they must deal with a broken data system that sends incomplete results in formats they can’t easily use.
After Brazil was the first emerging market to get a test drive of the Oxford University coronavirus vaccine, its Russia that is the first to complete human trials. Elena Smolyarchuk, chief researcher for the Russian Center for Clinical Research on Medications at Sechenov University, told TASS newswire on Sunday that human trials for the vaccine had been completed and those test patients will be discharged soon.
The study is enrolling 60 healthy volunteers aged 18-45, but the company hopes it will form the basis of trials of the drug as an outpatient treatment for patients who do not require hospitalization. Remdesivir is currently administered via IV.
Lopinavir is a drug against HIV; hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital has now discovered that the concentration of the two drugs in the lungs of COVID-19 patients is not sufficient to fight the virus.
Do you still believe that SARS-CoV-2, the virus responsible for Covid-19, is a hoax? Well a 30 year old male in San Antonio, Texas who recently attended a “Covid party” believing that the virus might be a hoax is now dead. He reportedly told nurses before he died this week at Methodist Hospital in San Antonio, “I think I made a mistake. I thought this was a hoax, but it’s not.”
